Rod Laver

Rodney George Laver is an Australian former professional tennis player, born in 1938, who was ranked the world's indisputable number one professional player from 1965 to 1969 and won 200 singles titles across his amateur and professional careers, the most of any tennis player. He is the only player in tennis history, male or female, to win the calendar year Grand Slam twice, in 1962 as an amateur and in 1969 during the Open Era, the only man to have done so since, and he also completed the Pro Slam of all three professional majors in 1967. He contributed to five Davis Cup titles for Australia, and both the Rod Laver Arena at the Australian Open and the Laver Cup tournament are named in his honor.
